Application filed November 30, 1903. Serial No. 183,137.

To LZ/7, who/11, t may concern:

Be it known that I, WILLIAM J. WATTnRs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Binder-Frames, of which the following isa specification.

This invention relates to loose-leaf binderframes; and its object is to provide a strong, substantial, and inexpensive frame of few parts which can be easily and quickly adjusted to secure or release the leaves.

In the accompanying drawings I have illustrated one form in which the invention may be embodied, and referring thereto- Figure 1 is a plan view of the frame. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is a detail view of a traveler. Fig. 4 is a horizontal sectional view on the line 4 4 of Fig. 3, showing also the cross-rails.

Like numerals of reference indicate corresponding parts in the several figures of the drawings, and, referring thereto, 10 is a back member, and 11 11 are relatively movable members to which the covers (not shown) are attached. These members are provided with interiitting ends of suitable construction, the drawings showing the ends 12 on the movable members arranged to work within vand close to the ends 13 on the back member,'and thus constructed the ends guide the movable members and assist in maintaining the members in proper relative position.

The movable members are adjusted relatively by a screw-rod 14, suitably mounted in bearings 15 on the back member and shaped at one end 16 to receive an operating-key. (Not shown.) In the embodiment of the invention shown in the drawings this rod is right and left threaded near its ends and carries travelers 17, each of which is provided with a threaded bore 18 to receive the rod and diagonally arranged corner recesses 19 Antifriction-rollers 21 are mounted on pins 22 within the recesses.

The travelers are simultaneously moved toward or from each other by operating the rod, and they engage the diagonally-arranged rails or rods 20 on the movable members to move said members relatively. These rails work between the rollers 21 and the shoulders 24 on the travelers, and they are secured to the movable members in any suitable manner. In the drawings the rails form part of skeleton plates 25 of triangular shape, which are fastened to the movable members with their projecting ends overlapping and the rails crossing each other. One of said plates is provided with a ange 26 to form a guide inclosing the adjacent edge 27 of the other. plate and also arranged to rest upon both of.

the movable members, as shown in Fig. 2;

` I may also support the rod between the trav.

the yusual manner on suitable supports 30,-

two of which are shown broken away in Fig.I 1 to better disclose the working parts.

My improved binder is very strong and durable in construction. It is composed offew parts and it can be manufactured at low cost. It is very easily and quickly adjusted to permit of the insertion or removal of leaves, and the character' of its construction permits of it being clamped very tightly upon the leaves to secure them rigidly in place. The construction is such that the travelers work easily' on the rails and operate to move the movablev members simultaneously toward or from each other and uniformly throughout the length of the frame.

Without limiting myself to the exact construction and arrangement of parts herein shown and described, what I claim, and desire to secure by Letters Patent, is-

1. A binder-frame comprisinga'back member and two relatively movable members, a

pair of diagonally-arranged rails carried by said movable members, a traveler carried by the back member and working on both sides of each rail, and means for moving the traveler on the rails to move the movable members bodily toward and from each other.

2. A binder-frame comprising a back member and two relatively movable members, di-

agonally-arranged rails on the movable members and crossing each other, a traveler engaging said rails, and means for moving said traveler longitudinally of the frame to move the movable members toward or from each other.

3. A binder-frame comprisinga back mem ber and two relatively movable members, a

pair of diagonally-arranged rails carried by said movable members at each end of the frame, travelers carried by the back members and working on both sides of said rails to move the movable members bodily toward and from each other, and means for moving the travelers simultaneously.

4. Abinder-franie comprising aback member and two relatively movable members, a pair of diagonally-arranged rails carried by said movable members at each end of the frame and crossing each other, a traveler working on each pair of rails, and a right and left threaded screw-rod carrying the travelers and adapted to be operated to cause the travelers to simultaneously move the movable members toward or from each other.

5. A binder-frame comprising a back member and two relatively movable members, diagonally-arranged rails carried by said movable mem bers, a traveler carried by the back members and recessed to receive the rails and working thereon, and means for moving the traveler on the rails to move the movable members bodily toward and from each other.

6. A binder-frame comprising a back member and two relatively movable members, diagonally-arranged rails carried by said movable members and crossing each other, a traveler working on said rails andl provided with corner-recesses to receive the rails and shoulders to engage one edge of the rails, antifriction-rollers engaging the opposite edge of the rails, and means for moving the traveler to move the movable members toward or from each other.

7. A binder-frame comprising a back member and two relatively movable members, a pair of diagonally-arranged rails carried b y said movable members at each end of the frame, a traveler engaging said rails, means for moving the traveler to move the movable members toward or from each other, and a collar operating loosely on the rod and connected to the movable members.

8. In a loose-leaibinder, in combination, two side members slidably supported with relation toeach other, two rods crossing each other, each rod being rigidly Asecured at one of its ends to one of said side members, and means for changing the point of' crossing of said rods to move said side members toward or from each other.

9. In a loose-lealil binder, in combination,

l a back member, two side members slidably supported with relation to said back member, two rods crossing each other, each rod being rigidly secured at one of its ends to one ot' said side members, and means for changing the point of crossing of said rods to move said side members toward or from each other.

10. In a loose-leaf binder, in combination, two side members slidably supported with relation to each other, two rods crossing each other, each rod being rigidly secured at one ot' its ends to one of said side members, a member embracing said rods at their point of crossing, and means for moving said member at a right angle with the line of movement of said side members.

1l. In a loose-leaf binder, in combination, two side members slidably supported with relation to each other, two rods crossing `each other, each rod being secured at one of its ends to one of said side members, a member embracing said rods at their point of crossing, and a shaft having a screw-threaded engagement with said member for moving said member at a right angle with the line of movement of said side members.

l2. In a loose-leaf binder, in combination, two side members slidably supported with relation to each other, two pairs of rods, the rods of each pair crossing each other, each rod being secured at one ot' its ends to one of said side members and the two pairs extending in opposite directions, a member for each pair of rods, said member embracing said rods at their point oi" crossing, and means for moving said embracing members in opposite directions.

13. In a loose-leaf binder, in combination, two side members slidably supported with relation to each other, two pairs of rods, the rods of each pair crossing each other, each rod being secured at one of its ends to one of said side members and the two pairs eX- tending in opposite directions, a saddle-block for each pair of rods, said saddle-blocks embracing said rods at their point of crossing, and a shaft having a screw-threaded engagement with said saddle-blocks for moving' said saddle-blocks in poposite directions.
